35. Chris Parnell

Era: 1998-2006

Never a show pony, but a workhorse. Next time you watch the "more cowbell" sketch, keep your eye on Parnell. Without his deadpan ballast, it's just Christopher Walken reading cue cards at four giggly boys. Dude did a lot of that, which is why he went on to greatness on 30 Rock and Archer.
